The invention discloses a plaster for preventing forestry pests poplar longicorn and relates to the field of pesticide and preparations thereof. A plaster for preventing poplar longicorn is prepared from the following raw materials in percentage by weight: 1-10% of chlorantraniliprole and 1-50% of acephate, and the remaining is assistant. The poplar bark is removed by spiral ringing from top to bottom on a poplar trunk with the vertical distance of 0.3-1.8m from the root to form a spiral groove which is 2-20cm in width. The depth of the spiral groove is from the poplar surface to a phloem thereof. The plaster is uniformly coated at the spiral groove. By being coated at the peeled bark, the plaster provided by the invention is good in adhesive force and persistence, simply and conveniently applied, thereby improving the medicament utilization ratio and reducing the environmental pollution. As the medicament can be sucked into plants through epidermis and the plaster provided by the invention has certain contact action, the pests can be prevented from crawling up and down on the trunk so as to greatly reduce harm to the plants.

The invention provides a leak-proof portable soap box. The box comprises a box body with an opening formed in the upper end and a box cover matched with the opening formed in the upper end of the boxbody, water leaking holes are formed in the bottom of the box body, supporting frames are detachably and fixedly arranged on the opposite two sides of the box body, the box body is supported and fixedthrough the supporting frames, and the vertical distance between the bottom of the box body and the bottoms of the supporting frames is greater than or equal to the thickness of the box cover; the box cover is arranged on the box body in a covered mode or arranged at the bottom of the box body with the opening upward, the bottom of the box cover is of a sealed structure, and supporting frame embedding grooves are formed in the bottom of the box body. The leak-proof portable soap box aims at solving the problems of unreasonable design and desktop/tabletop contamination due to bottom water leakage and the like. The invention belongs to the field of daily use tools.

The invention discloses a wheeled crane operation vibration-proof device, a system, a method and a wheeled crane. When the wheeled crane is used for operation, supporting legs arranged on the two sides of the wheeled crane are stretched out and lifted so as to set up the wheeled crane. The wheeled crane operation vibration-proof device comprises a receiving device used for receiving data of vertical distance between a vehicle frame and an axle of the wheeled crane; a controlling device used for operation of at least one of the following steps: lifting operation of the supporting legs is controlled based on the vertical distance between the vehicle frame and the axle so as to control contact degree of tyres with the ground; or an indicating device is controlled to send indication signals based on the vertical distance between the vehicle frame and the axle. According to the wheeled crane operation vibration-proof device, contact degree of tyres with the ground is controlled based on the vertical distance between the vehicle frame and the axle, vibration damping effects can be improved without using of specialized vibration damping equipment, and vibration of the integral body of the vehicle frame parallel to the ground is reduced preferably.

The invention discloses a prediction method for horizontal deformation of a high-core-wall rock-fill dam in a construction period, which comprises the following steps of: selecting a reference surface(generally a foundation surface) on the high-core-wall rock-fill dam, determining vertical distances from each monitoring point to the reference surface and the surface of the dam body according to the horizontal deformation monitoring points distributed in the dam body and the positions of the horizontal deformation monitoring points, and establishing a space coordinate system; determining the spatial position of each monitoring point; stress deformation and creep deformation of the deformation monitoring points in the river direction are calculated according to the horizontal deformation physical causes; calculating stress deformation and creep deformation of the deformation monitoring points in the transverse river direction; and according to the stress deformation and creep deformation of the deformation monitoring points along the river direction and the stress deformation and creep deformation of the deformation monitoring points along the transverse river direction, calculatingthe horizontal deformation of the deformation monitoring points along the river direction and the horizontal deformation of the deformation monitoring points along the transverse river direction.
